American Petroleum Institute (API) standards
Standards and technical regulations drive economic growth, technology development, and global trade. API standards convenes subject matter experts across segments to establish, maintain, and distribute consensus standards throughout the oil and natural gas industry. Their purpose is to enhance operational safety, environmental protection and sustainability across the industry, especially through global adoption. The standards are developed under API’s American National Standards Institute accredited process, ensuring that the API standards are recognized not only for their technical rigor but also their third-party accreditation which facilitates acceptance by state, federal, and increasingly international regulators
API has more than 700 standards.
API standards committees
API's Standards Committees work to maintain standards through its specific area of interest.
Committee on Standardization of Oilfield Equipment and Materials (CSOEM)
Provides leadership in the efficient development and maintenance of standards that meet the priority needs of the domestic and global oil and gas exploration and production industry by minimizing needs for individual company standards, promoting broad availability of safe, interchangeable oilfield equipment and materials, and, promoting broad availability of proven engineering and operating practices.
Committee on Refinery Equipment (CRE)
Promotes safe and proven engineering practices in the design, fabrication, installation, inspection, and use of materials and equipment in refineries and related processing facilities.
Pipeline Standards Committees
Dedicated to developing, revising, and approving consensus standards for the pipeline industry. These committees are comprised of technical experts, operating companies, vendors, consultants, academia, and regulators to create standards that facilitate safe operation and maintenance of pipelines.
Safety and Fire Protection Committee (SFPS)
Provides proactive safety and occupational health leadership and expertise to the industry, API committees and member companies. The SFPS seeks to advance and improve the industry’s overall safety and occupational health performance by combining resources to identify and address important public, employee and company issues.
API Marketing Committee
Provides leadership in developing and maintaining standards on the wholesale and retail distribution, including tanker truck transportation, of refined petroleum products such as gasoline and diesel fuel to business, industry, government and public consumers. The Standards committees address commonly asked questions for consumers.
Committee On Petroleum Measurement (COPM)
provides leadership in developing and maintaining cost effective, state of the art, hydrocarbon measurement standards and programs based on sound technical principles consistent with current measurement technology, recognized business accounting and engineering practices, and industry consensus.This is accomplished through the committee's and API’s leadership role in the national and international standardization community in the development, publication, promotion, and revision of petroleum measurement standards, through its subcommittee structure, and through elimination of duplicative efforts.
API Upstream standards committees
In SPE's PetroWiki will focus on the Upstream committees only.
API Committee on Standardization of Oilfield Equipment and Materials (CSOEM).
The Committee on Standardization of Oilfield Equipment and Materials (CSOEM) consists of several subcommittees. Each subcommittee works with a specific area of exploration and production of oilfield equipment. Below is a list of the subcommittees and the areas they work with. You can access these subcommittee pages using the links at the top of the page.

Drilling and Production Operations Subcommittee (DPOS)
The Drilling and Production Operations Subcommittee (DPOS) conducts advocacy and promotes sound practices on drilling and production operational matters. In this role, the DPOS acts on existing and emerging issues, and develops recommended practices and guidelines. Also, it serves as a forum for coordination with government agencies and other domestic and international industry groups to facilitate communications on operational, safety, and training issues that may impact exploration and production activities.
